ABSTRACT:
A controller refers to an address translation table and searches for the logical address of a valid logical block used by a host computer. Then, the controller reads from a disk array only a physical stripe that includes the physical block of a physical address corresponding to the valid logical address. Based on the read physical stripe, the controller restores data of a failing disk drive and writes the restored data in a spare disk drive that is used in place of the failing disk drive.
